CONVEYER.

To all whom it may concern.-

' specification, in which- Figure 1 is a side elevation, partly in sec`tion, showing a portion of my improved con- -veyer. Fig. 2 is across-section on the line II II-of Fig. 1. Figs. 3 and t are detailviews of the eccentrics which I employ. Fig. 5 is a view showing thedriving mechanism for the main shaft. 'Fig` 6 shows a modification, andFig. 7 is a plan view of the same on a larger scale.

' The purpose of my invention is to provide means for conveying metalfrom one part of a mill to another.- It is especially adapted to conveyhot pieces of metal and simultaneously cool them in their passage.

' The mechanism is characterized by simplieity of construction andeconomy in maintenance and operation, which areof great importance in amachine of thiskind.

The drawings show the preferable construction of the apparatus; butthose skilled in the art will be able to modify it in various ways.

The conveyer comprises a series of xed rails 2, s et parallel to eachother and constituting a cooling-bed and conveying-table. They aresupported upon suitable posts or standards 3, to which they are fastenedby clamps 4 to assure rigidity of construction. The moving mechanismconsists of rails or beams 5, which are set in the spaces between thefixed rails 2.and are preferably connected by cross-bars 6, which causethem to move in unison. These movingbeams are supported by boxes 7,which inclose eccentrics 8, forming part of transverse shafts 9, drivensimul-4 taneously by gearing 10 from a main shaft 11. The rotation ofthe eccentrics 8 by theshafts 9 imparts a rotative motion to the movingbeams 5, causing them to alternately rise and lower, and in the part oftheir motion which is above the stationary rails 2 they move forward ina circular arc, the radius of which is the distance from the centers ofthe eccentrics to the axis of the shafts 9. Therefore any articles whichare placed upon the rails 2 Specication of Letters Patent.

will be engaged by the moving beams 5 and will be moved forward step bystep, being raised from the fixed rails, carried forward,

and then deposited thereon while the moving rails are describing theupper half of their circular movement and resting on the fixed railswhile the moving beams are describing the lower half of their circularmovement in a backward direction. The length of each step thus impartedto the articles by the moving beams is determined by the throw of theeccentrics, and the rapidity of the motion is determined by the speed ofthe driving-gearing.

The moving beams are provided with we aring-pieces 12, preferably ofcast-iron, which afford transverse openings 13 for the passage of air,so that the beams themselves are pre- 7 0 vented from being overheatedby hot articles which are being carried.

In Fig. 5 I show means for driving the main vshaft l1, consisting of aworm-wlieel 14 and vworin 15, which is rotated by a suitable motor 16 orsome other power connection.

In Figs. 3 and A I show means by which the throw of the eccentrics canbe varied to suit the requirements of the particular use to which theconveyer is put. of a disk 8, having an elongated slot 17 litting on asquared portion 9 of the shaft 9.

The slot is longer than the cross-section of the shaft andaffords roomfor the intel-position of liners 18. or more of the liners from one sideof the shaft to the other the degree of eccentricity may be varied. Theeccentric is held on the shaft and the shaft held in contact with theEach eccentric consists 8-0 By changing the position of one liners by aset-screw 19, set in a countersunk recess in the eccentric, as shown inFig. 4.

In Fig. 6 I show a modification of the ap-l paratus in which the fixedand stationary rails are set on an incline, and for the, purpose ofpreventing the material conveyed thereby of moving beams and rotaryeccentrics supporting the moving beams and arranged to' IOO impartthereto an upward motion and a forward motion above the fixed supports;substantially as described.

2. A conveyer comprising' a series of fixed supports for the material tobe conveyed, a set of moving' beams, rotary eecentrics supporting themoving beams and arranged to impart thereto an upward motion and aforward motion above the fixed supports, a shaft 1l extending parallelwith the moving beams, and gearing connecting the eccentrics ,therewith;substantially as described.

3. A conveyer comprising' a series of fixed supports, a set of movingbeams, rotary eccentrics supporting' the moving beams and arranged toimpart thereto an upward motion and a forward motion above the fixedsupport, and means for varying the throw of the eee-entries;substantially as described.

4. A conveyer comprising a series of fixed supports set in the sameplane, and a set of parallel moving beams mounted on eccentries andadapted to have a rotary motion extraiding above and below the level ofthe lixed supports, said moving beams having iaengs provided withair-passages; substantialh' as described.

5. A conveyer comprising a series ol lixed supports set in the sameplane, and a set of moving parallel beams mounted on eccontrics andadapted to have a rotary motion extending above and below the level ofthe lixed supports, said eceentrics being adjustable in throw;substantially as described.
